if II is the invoke instruction, you can get the names as follows:

  "@__cxa_throw": II->getCalledFunction()->getValueName()
  "@_ZTi": II->getOperand(4)->stripPointerCasts()->getValueName()

The first one won't work for indirect calls.  The second one
won't work in more complicated situations.  Why do you want
the names anyway?

Ciao,
